Well everyone hates it when you died in a DM and lost all your lifes, people keep joining and the minigame never ends. My idea was when people spawn they go to the "no-life-screen" where you can spectate and when minigame ends they spawn.
CucumberDude has done this.
So like a spectating team, right? Like in Team Fortress 2 arena maps, for example.
I like this idea.Maybe when this is done, someone can make a shooting gallery for the less-skilled players to practice on after they die.
